What is a teen sleuth supposed to wear?

Today, while shopping, I noticed a new trend theme in a lot of stores accessories. Nancy Drew-esq hats, gloves, and even magnifying glasses in a few.

They are still writing them but the older ones are the best (original author Carolyn Keene died about 10 years ago) There was that Emma Roberts movie a few years ago based on the series which in a way made fun of bookish Nancy but really got her style perfectly.
